There’s literally nothing in this article that you couldn’t replace “token” or “coin” with “contract” or “membership” and have it work exactly the same. The idea of selling contracts against future income is interesting but putting the blockchain here is yet another solution in search of a problem.
Blockchain isn’t magic. It can’t do very much “new”. But if it can take something old (contract) and make that more accessible to more potential contract buyers/sellers, then that’s actually interesting.
Technology that makes slow complicated things fast and easy can have a lot of impact.
I won’t be selling shares of myself nor buying shares of others. But this we’re close to the point where blockchain actually provides real value beyond tulip speculation.
